Sum of oxidation state (magnitude) and coordination number of cobalt in Na Co bpy Cl 4 is

Step-by-step solution

2,2′-Bipyridine is an organic compound, This colorless solid is an important isomer of the bipyridine family. It is a bidentate chelating ligand, forming complexes with many transition metals. There is one bidentate ligand and four monodentate ligand attached with Co metal ion. So, Coordination no. will be = 6 This bpy ligand has no net charge. and chloride ion has -1 charge. So, Oxidation state of metal ion will be = 3 Their sub will be = 6 + 3 = 9
